South Korea appears to have been the target of a cyber-attack from the North after computer systems at broadcasters and banks in the country simultaneously crashed today.
The shutdown came just days after North Korea was hit by cyber-attacks which temporarily disabled a number of websites in Pyongyang and which it blamed on the U.S. and South Korea.
The two nations have been engaged in an increasingly aggressive war of words in recent weeks, with North Korea threatening war after cancelling the decades-old ceasefire between the neighbours.
Officials at the two South Korean public broadcasters KBS and MBC said that all computers at their companies shut down at 2pm (5am GMT). The officials said the shutdown was not immediately causing damage to their daily TV broadcasts.
YTN cable news channel reported the company’s internal computer network was completely paralysed.
